Windows: enable WSL2 and Docker Desktop
Windows users only; Mac/Linux users skip to the next step. If Ubuntu in WSL2 is not installed, run the command below in PowerShell as Administrator, restart if requested, then open Ubuntu and create its Linux username/password. Install Docker Desktop, choose its WSL2 engine, and enable Settings → Resources → WSL Integration → Ubuntu. From here, run Rakazo’s Bash commands in Ubuntu, not PowerShell. Keep the installation under ~/rakazo in Ubuntu.
